SLIDING GATE.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed March 27, 1916. Serial No.'87,065.

To all whom-it may concern:

Be it known that I, THOMAS J. BROWNE, a subject of the King of England,residing at Oldham, in the county of Halifax, in the Province of NovaScotia andDominion of Canada, have invented certain new and usefulImprovements in Sliding Gates, of which the following is aspecification.

This invention has relation to certain new and useful improvements ingates and it contemplates, primarily, the provision of a novel form ofgate and supporting means therefor, whereby the gate may be easily andquickly operated with but little exertion on the part of the operatorand which consists of but a few simple parts whereby it not likely toget out of order.

A further object of my invention is to provide a device of the type inquestion that is extremely simple in construction, strong and durable,and highly practical from both the standpoint of the user and thestandpoint of the manufacturer; and which, it is believed, may bemanufactured at a comparatively low cost.

Various other objects and advantages will become apparent during thecontinuance of the following description.

These objects are accomplished by such means as are shownin theirpreferred form in the accompanying drawings, described in the followingspecification and then more specifically pointed out in the appendedclaim.

In the accompanying drawings wherein like characters designate likeparts throughout the several views:

Figure 1 is a view in front elevation showing my invention, as in itspreferred embodiment, the gate proper being in a partly extendedposition;

Fig. 2 is a view in section taken on line 22 of Fig. 1;

Fig, 3 is a view in section taken on line 3-3 of Fig. 1; and

Fig. 4 is a fragmentary view of the gate and gate frame, showing moreclearly the relative position of the members. 7

In the drawings, A designates a suitable support in connection withwhich my invention has been shown, but it is to be fully understood thatI am not limited to this specific application, since the gate may beadvantageously used in connection with other types of supports, withinthe discretion of the user.

10 and 11 designate relativelyspaced upper and lower track members thatcarry suitably curved arms 12 and 13 that have connection with thesupport A as designated at 14. At their inner ends, tracks 10 and 11are.connected by means of a member 15 that also carries a suitablycurved arm 16 for connection with the support A, as'at 17. In thepresent embodiment, the track ways are formed integral with connectingmember 15 and are preferably constructed of a length of piping or othermaterial, substantially circular in cross section, whereby the trackspresent opposed faces of substantially convex configuration. The purposeof this construction will subsequently appear.

At their forward ends, tracks 10 and '11 are'slightly reduced as at 18and they are connected by spaced vertically disposed sto members 19 and20 whose extensions 21 t the side of the reduced portions 18, as clearlyillustrated in Fig. 4. After the arrangement of the parts in thisposition, a suitable fastening member, such as shown at 22 may be passedthroughthe extensions 21 and the reduced portion 18, thereby insuring acompletely rigid structure.

The gate structure of the present embodiment, consists of a suitablydisposed frame 23 covered by a sectionof reticulated material 24, suchas wire mesh, the same operatingbetween stop members 19 and 20, asillustrated in Fig. 4. At its rear end, frame 23 carriesrelativelyspaced hanger bearings 25 and 26 that in turn support guidewheels 27 and 28 which have circumferential grooves fitting the opposedfaces of tracks 10 and 11. .At its forward end, frame 23 carries avertically disposed stop 29 that projects laterally thereof, as in Fig.4, and

which is designed'to abut against stops 19 and 20 to limit the inwardmovement of the gate structure, as is obvious.

I also provide the lower track 11 with a supporting bearing 30 adjacentits forward endthat carries a supporting roller 31 which has itscircumferential grooved face fitting the lower frame member of the gatein order to support the latter in its true plane, at all times. Therollers 27 and 28 serve to properly support the gate, at all times butby 7 providing the additional supporting roller 31, it is apparent thatthe strain upon the other rollers, as well as the hanger bearings 25 and26 is materially relieved. This construction not only insures thelongevity of the hanger bearings 25 and 26 but also serves to retain thegate in its true plane, as above stated and prevents the usual saggingthereof. v

From the foregoing, it is believed that the advantages and novelfeatures of my inven tion will, be readily understood and, therefore,further detail description is deemed unnecessary.

In reducing my invention to practice, I find that the form referred toherein as the most practical and preferred embodiment of my invention,is the most efficient,- but realizing that certain conditions willnecessarily ,vary in concurrence with the adoption of my device, Idesire to emphasize the fact that various minor changes in the de tailsof construction and in the proportion of parts may be resorted to whenrequired, without sacrificing any of the advantages of my invention, asdefined in the appended claim. 1 v c Having thus fully described myinvention, what I claim as new and desire to secure by Letters Patent isIn oon'ibmation, a support, a member bent to provide upper and lowerparallel track elements and a vertical element connecting the rear endsof the track element, said track elements having their outer endsreduced, transversely spaced stop members having lateral extensionsoverlapping the reduced ends of the track elements and secured thereto,laterally extendingarms connecting the track elements and said verticalelement to the support, a gate disposed to operate between thetransversely spaced stop members, wheels at the rear end of the gate totravel upon the track elements said gate having a laterally projectingmember at its forward end to close the space formed between'thetransversely spaced, stop 1nembers and engage the latter and limit theinward sliding movement of the gate, and a roller disposed upon theforward end of the lower track element to act jointly with the wheels atthe rear end of the gate to hold the latter in proper position.

In testimony whereof I aflix my signature in presence of two witnesses.
